Use ER Assistant to draw your diagram. Draw a generalization hierarchy containing Employee, Administrator, and Faculty entities. The Employee entity is the supertype, and the Administrator and Faculty entities are the subtypes. The Employee entity has attributes as follows: EmpNo (primary key), EmpName, and EmpAddress. The Administrator entity has attributes as follows: AdmTitle, AdmContractLength The Faculty entity has attributes as follows: FacTenure, FacRank The generalization hierarchy should be disjoint but not complete.

Use ER Assistant to draw your diagram. Draw a self-referencing entity type for the Employee entity type for which an employee is supervised by a maximum of one other employee and doesn’t have to be supervised by any employee at all. Conversely, an employee can supervise zero or many other employees. The attributes of the Employee entity are as follows: EmpNo (primary key), EmpName, EmpAddress.
create an Enhanced Entity-Relationship (EER) diagram based on the provided information. Based on the following description, try creating the diagram using a tool such as draw.io, Lucidchart, or any other ER diagram tool: Entities: Person: person_ID (PK), name, address, birth date, phone number Subtypes: Employee, Physician, Patient, Volunteer Visit: date (PK, partial identifier), comments Care Centre: care_centre_ID (PK), name, location Laboratory: lab_ID (PK), name, location Bed: bed_number (PK), room_number, care_centre_ID (FK) Item: item_number (PK), description, unit_cost Treatment: treatment_ID (PK), treatment_number, treatment_name, treatment_date, treatment_time, results Relationships: Works_In (Person - Care Centre): Person (1, M) ----< Works_In >---- (1, M) Care Centre Assigned_To (Employee - Care Centre): Employee (1, M) ----< Assigned_To >---- (1, M) Care Centre Assigned_To (Physician - Care Centre): Physician (1, M)…
Draw an ER-Diagram for this situation and place minimum and maximum cardinalities on the diagram? Entity type: • EMPLOYEE with attribute: EmpID , Name (Firstname :besan, Lname) , Address :Amman, Birth_of_Date25/5/02 . • DEPARTMENT with attribute : DeptID , DeptName , Loc Relationship: Works_in Relationship between EMPLOYEE and DEPARTMENT and each employee is works in zero or many department and each department worked by one or many employee.
Draw an ER diagram for the following scenario- • An instructor has an ID, a name, and a phone number. An instructor teaches a course • A course has a code, course name, credits, and an instructor. Each course uses a textbook. • A textbook has ISBN, name, publisher, editor, and authors. Your ER diagram should have entities, attributes, composite attribute, multivalued attribute, key attributes, binary relationships, and a total participation. Explain your rationale behind each design choice. Please draw the ER diagram on paper showing all seperate parts for each instructor, course and textbook. Showing each connection seperately and explaining which connection is which
Create an entity-relationship diagram for the three entities showing the correct cardinalities. Save and print a copy.
An instructor has several phone numbers. When reducing the ER diagram down to a schema this must be addressed. Which of the following statements are true? a. an instructors phone is what is known as a multi-valued attribute b. a multi-valued attribute of an entity is expressed as a separate schema with attributes including the primary key of the original entity and the multi-valued attribute c. the instructor should have a column for each type of phone number d. multi-valued attributes must be flatted out to a separate attribute for each component
Draw an ER diagram for the EMU Slimming Center based on the specification given below. Case Study 01 There are many dietitians in the center. There are also many clients in the center. A dietitian gives a menu to a client every week. Many diet menus are available. A diet menu consists of many food items and each food items belongs to one food category. Instructions • Identify the relationship between Entities (clearly showing the cardinality and participation)
b. Draw an Entity Relationship diagram from each of the following descriptions. Include the attributes, primary keys (underlines) and the relationships in the diagram (like relationship in Access). i. Each of the department has many employees assigned to it, but each employee works for only one department. if. A customer can rent many videotapes from the video store. Each of the videotapes can be rented to many customers.
Draw an ERR diagram with this information: EER Diagram for Royal Victoria Hospital Information System Assumptions: The diagram focuses on the entities and relationships. Attributes with cardinality are assumed to be single-valued. Dates are assumed as identifiers for visits. Entities: Person: (person_ID, name, address, birth_date, phone_number) Employee: (inherits from Person, date_hired) Nurse: (inherits from Employee, certificate) Staff: (inherits from Employee, job_class) Technician: (inherits from Employee, skill) Physician: (inherits from Person, speciality, pager_number) Patient: (inherits from Person, contact_date, resident_flag) Outpatient: (inherits from Patient) Resident: (inherits from Patient) Visit: (date, comments, outpatient_ID) Care Centre: (name, location) Laboratory: (name, location) Bed: (bed_number, room_number, care_centre_ID) Item: (item_number, description, unit_cost) Treatment: (treatment_ID,…
Let's break down the information into entities, attributes, and relationships: Entities: 1. Ship - ShipID (Primary Key) - ShipName - ShipType 2. Captain - CaptainID (Primary Key) - CaptainName - CaptainLicense 3. ShipmentTrip - TripID (Primary Key) - DeparturePort - ArrivalPort - RouteDetails 4. ShipmentManifest - ManifestID (Primary Key) - Date - GoodsList 5. Goods - GoodsID (Primary Key) - GoodsName - GoodsType (BM or LM) 6. Port - PortID (Primary Key) - Street - City - State - PostalCode - Country Relationships: - Ship to ShipmentTrip (Many-to-Many): - Ship can participate in multiple ShipmentTrips, and a ShipmentTrip can involve multiple Ships. Create a junction table `Ship_ShipmentTrip` with attributes `ShipID` and `TripID`. - Captain to ShipmentTrip (Many-to-Many): - A Captain can be assigned to multiple ShipmentTrips, and a ShipmentTrip can have multiple Captains. Create a junction table `Captain_ShipmentTrip` with attributes `CaptainID` and `TripID`. - Captain to Ship…
Create an Entity Relationship diagram (ERD) for the following scenario indicating the identifiers and cardinality constraints. A division operates many departments, but each department is operated by only one division. Each division must have at least one department and each department must belong to a division. A department employs many employees, but there may be a department with no employees. Division is characterised by Divisionid and Divisionname and the attributes of department include Deptid and Deptname. Majority of employees called “dept_emps” are employed by a department. However, there are also employees known as “free_lance_emps” who are not assigned to any department. A department may own many projects, but there may be a department with no projects. Employee is characterised by empid, empname, emptype and address. Both dept_emps and free_lance_emps can work on many projects, but there are employees who do not work on any project. A project has at least one employee…
